Maximum dose: 2400 to 3600 mg/day; doses up to 2400 mg/day have been well tolerated in long-term studies; doses of 3600 mg/day have be used in a small number of patients for a relatively short duration and have been well tolerated. Dosage adjustment in patients 12 years of age and older with renal impairment or undergoing hemodialysis is recommended, as follows (see dosing recommendations above for effective doses in each indication): TABLE 1. NEURONTIN Dosage Based on Renal Function. In adults with postherpetic neuralgia, gabapentin may be initiated on Day 1 as a single 300 mg dose, on Day 2 as 600 mg/day (300 mg two times a day), and on Day 3 as 900 mg/day (300 mg three times a day).
